Letters Patent No. 9( ),949, dated June 8, 1869.

IMPROVEMENT IN LIGHTNING-RODS.

The Schedule referred to in these Letters Patent and making part of thesame.

To all whom it may concern:

Be it known that I, THEODORE T. KINSEY, of Philadelphia, Pennsylvania,have invented'a new and us ful Lightning-0onductor and I do herebydeclare that the following is a full and exact description thereof,reference being bad to the annexed drawings, forming part hereof, inwhich p I Figure 1 is a perspective view of two 'sections of theconductor united.

Figure 2, a' similar view of the same sections separated, this viewbeing intended to exhibit the recesses formed in thestrips, or plates ofone section, to facilitate the uniting of any two contiguous sections.

My invention consists of a lightning-conductor, the body of which isformed of strips of sheet-copper or iron, first severally foldedlongitudinally so as to form a triangle or angle, then fastened togetherwith rivets inserted through the angles at short intervals, the wholebeing then twisted so that the several strips assume the spiral formshown in the drawings; or the conductor may consist of any number ofseparate sec tions, each composed of folded strips, as aforesaid, theseveral sections employed being then joined at their ends, in' themanner illustrated in the drawings, and the whole being then twisted asaforesaid.

In the drawingswire, as at g, fig. 1.

a represents one strip, and b, the other strip, they being each foldedlongitudinally, as shown.

a are the rivets by which the folded strips are fast, ened together.

When two sections are intended to be united, each of the strips of oneof such sections has a narrow slot, (1, fig. 2, about one-half inch indepth, formed in it.

The ends of the strips of the other section are then inserted in theslots (1, and the two sections arefirmly united, either with rivets, asat f, or by being tied with I prefer to use rivets for this purpose.

No point or head of the conductor is represented, but the ordinary pointis riveted, or otherwise atfixed to the body of the conductor.

Having thus described my invention,

I claim, and desire to secure by Letters Patent A lightning-conductor,the body of which consists of two strips of sheet-metal foldedlongitudinally, riveted together through their angles, and twisted intoa spiral form, substantially as set forth.

THEODORE '1. KINSEY.
